Patent DE-3838767-A1 (DE)
Title: Hydrostatic/mechanical power-shift transmission with a continuously variable effect and a high-quality gear change
Inventor: JARCHOW FRIEDRICH PROF DR ING
IPC: E02F9/20
Filed: 1988-05-09
Abstract: The transmission consists of a four-shaft planetary gear mechanism and a continuously variable hydrostatic transmission arranged in parallel with it and of further gear wheels, selector clutches bringing about a plurality of gears in each of which the hydrostatic transmission effects continuously variable adjustment of the transmission ratio of the transmission as a whole, the gear change taking place at synchronous speeds of rotation without interruption of the tractive effort. An electronic/hydraulic control and regulation system ensures a jerk-free gear change. In particular, it performs a correction of the displacement volume of the variable displacement machine of the hydrostatic transmission appropriate to the respective leakage oil flows upon each gear change. Such transmissions are advantageously suitable for motor vehicles since, apart from having a very smooth gear change, they have good efficiencies and a wide transmission-ratio adjustment range.

Title: Method for the regulation, control and/or monitoring of a web coating drying unit
Inventor: LALLI ESKO
IPC: B05C11/10
Filed: 1989-01-19
Abstract: Method for the regulation, control and/or monitoring of the drying of the coating of a web (W). A paper web (W) is guided through coaters (30) in which coating colour is applied to the web, after which treatment the web (W1) is guided to the coating drying unit. In the method, a computer (110) is used for process control and a process model is applied which is established on the basis of trial runs, on-line measurements and/or the drying theory of the process to be controlled. The process model calculates at least the temperatures of the paper web to be coated, the dryness contents of the coating layer after each of the said dryers, and the position of the solidification region of the coating. From a so-called recipe card, grade-specific desired value parameters of the relevant web grade are put into the drying model. New output values are entered into the simulation program at specific time intervals, for which measured values (a-k) of the process parameters obtained from the various measuring transmitters (1-25) of the coating drying process are used. To minimise the inaccuracies of the process model, an adaptive process model is used in the method, for which purpose one or more specific parameters in the process model are maintained as variables, which one or more parameters are adapted in the correct direction, proceeding from the new process output values, in such a way that the process model [lacuna] as a result for the ...

Patent DE-3914587-A1 (DE)
Inventor: KUEHN HANS-ROBERT
IPC: G11B19/22
Filed: 1989-05-03
Abstract: Such playback devices, e.g. CD players, are fitted with a loading and release mechanism for the recording substrate, the CD. However, before a CD is released from the CD player after playback or the pressing of a "STOP" button, it must be stopped to prevent damage to its sensitive surface. Because the mass and diameter of CDs varies and there are also mini-CDs, the CD may still be rotating during the release process. To prevent damage during the release process, the CD is safely and rapidly brought to a standstill by generating the necessary braking force dependently upon the rotation speed of the CD. CD players, video disc players, magneto-optical devices, DRAW disc players.
